Perfect for Home Assistant

Works flawlessly with ESPHome. I replaced my old PIR sensors with these and the false negatives are gone. It detects me sitting still at my desk.

Steep learning curve

Hardware is good, but documentation could be better for beginners. Had to search forums to understand the UART command structure.

Good sensitivity

Detects breathing well, but configuration took some time to get right. Once tuned, it is very reliable for bathroom lighting automation.

Better than PIR

No more lights turning off while I am reading quietly. The millimeter-wave technology is a game changer for smart home presence detection.

5 FAQ

Q: What is the default UART baud rate?

A: The default baud rate is 115200. This can be configured via the UART protocol commands if needed.

Q: Is this module compatible with ESPHome?

A: Yes, this sensor has native support in ESPHome and can be easily integrated into your Home Assistant setup.

Q: Does it detect pets or only humans?

A: It detects motion and presence based on size and micro-movements. Small pets may trigger it depending on sensitivity settings.

Q: What is the maximum detection distance?

A: The maximum detection range is approximately 6 meters in an open environment, though walls may reduce this range.

Q: Can I power this with 3.3V?

A: No, the module requires a stable 5V DC power supply. Using 3.3V may cause instability or failure to operate.
